Abstract: PURPOSE:To keep the density of a developed image constant by providing a residual potential measuring means for measuring the residual potential of an exposing part of a photosensitive body, and a control means for controlling a developing bias in accordance with a measured value by this residual potential measuring means. CONSTITUTION:Prior to the start of image recording, a photosensitive body 1 is rotated, its surface is electrified uniformly by an electrifier 2, and the surface potential after the electrification is measured by a surface potential measuring instrument 12, and inputted to a control circuit 16. Subsequently, the electrified surface of the photosensitive body is exposed by an exposing device 4, but in this case, the exposing device 4 exposes continuously a suitable area of the photosensitive body 1, so that the potential measurement by a residual potential measuring instrument 15 is facilitated. Next, the residual potential measuring instrument 15 measures the residual potential of the exposed part, outputs it to a control circuit 16, and the control circuit 16 determines the surface potential and a value of the developing bias in accordance with the measured residual potential and corrects an output voltage of an electrifier use power source 3 and a developing bias use power source 6. In such a way, a difference between the developing bias and the residual potential is set as prescribed, and the density of a developed image can be set to a prescribed density irrespective of the residual potential.

Title: Winding device for sheet like material
Inventor: INAGAKI TAKESHI
IPC: B65H23/025
Filed: 1995-03-31
Abstract: PURPOSE: To wind a sheet, if it is glassine paper, like common paper without winding wrinkles by providing spirally protrusive streak or grooves in order to permit trapped air to escape. CONSTITUTION: On the start of winding, a paper sheet P is turned upward onto a first winding drum 1 from the under side of the drum 1 and led to a nip portion formed by the winding drum 1 and a winding body 20. In the case where the first winding drum 1 is provided with spiral grooves, air trapping is restricted, which occurs by trapping air under the outermost layer of the sheet as the paper sheet P runs. At the time when an air trapped portion reaches the uppermost portion of the winding body 20, a rider roll 3 presses the surface of the winding body 20. Since the rider roll 3 is provided with spirally protrusive streaks or spiral grooves 4 around the surface of the rider roll 3, trapped air can be removed which still remains under the uppermost layer of the paper sheet after the grooves of the first winding drum 1 acted so as to prevent air inclusion.

Title: Method for determining degree of deterioration of fluorescent magnetic powder liquid
Inventor: MORI TAKESHI
IPC: G01N27/84
Filed: 1987-03-27
Abstract: PURPOSE:To exactly decide the degree of deterioration of a fluorescent magnetic powder liquid by projecting excitation light to the fluorescent magnetic powder liquid and determining the amt. of the magnetic powder by electrical measurement. CONSTITUTION:The fluorescent magnetic powder liquid 1 circulated in a piping for the fluorescent magnetic powder liquid is passed in a deterioration decision pipe 2, by which the quantity of fluorescence is calculated from the quantity of the fluorescent rays per unit volume and the amt. of the magnetic powder is calculated from electrostatic capacity, respectively. A fluorescent coating compd. is gradually stripped from the fluorescent magnetic powder when the number of use of the fluorescent magnetic powder liquid increases. The fluorescent magnetic powder and the magnetic powder from which the fluorescent coating compd. is stripped are stuck to the material to be inspected but the stripped fluorescent coating compd. is not stuck thereto on continuation of the flaw detection. As a result, both the quantity of fluorescence and the amt. of the magnetic powder decrease but the decrease rate of the amt. of the magnetic powder is larger and, therefore, a difference arises in the respective detected values. A comparison decision part 10 emits a warning signal when the difference increases to a specified value or above.
